Try to return those lamps. They're just going to dry out the air and your snake will most likely have problems shedding. Ideally, you should get an under tank heater (UTH) and connect it to a thermostat to dial in the correct temps. If you can't get a decent thermostat, get a lamp dimmer (rheostat). You can manually adjust the temps using that, but you just have to monitor it more if the temps in your room fluctuate very much. You'll probably want to get another hide. The half logs don't work too well for Balls because of the two openings. You can make hides out of clay pots, plastic bowls, or even a cardboard box.

Good luck!
